EM Observations and Differential Scanning Calorimetric tudies of New and Sterilized Nickel-Titanium Rotary ndodontic Instruments

f bstract canning electron microscopy (SEM) and differential canning calorimetric (DSC) studies were utilized to nvestigate surface and microstructure of two brands of otary nickel-titanium (NiTi) endodontic instruments, in he as-received condition and after subjection to 1, 6, nd 11 sterilization cycles. A total of 66 ProFile (n 3) and Flexmaster (n 33) files were examined. SEM bservations ind...

Patient-specific instruments: advantages and pitfalls

Patient-specific instruments (PSI) aim to improve the accuracy of total knee replacement (TKR) based on computer-assisted preoperative planning. In this work, the authors describe the advantages and pitfalls of PSI based on their clinical experience. The main conclusion of this work is that PSI has direct impact on the logistical and technical features of TKR with some advantages and pitfalls.

The indirect cost of Patient-Specific Instruments.

PURPOSE To calculate the indirect costs of Patient Specific Instruments (PSI) based on an opportunity cost, cost of efforts and a supply chain cost model to compare PSI for value with conventional total knee arthroplasty (TKA). METHODS In 81 patients the total (direct+indirect) cost of PSI-assisted TKA was compared with conventional TKA. Surgical times and coronal mechanical alignment were me...

An evaluation of anesthesia patient satisfaction instruments.

The purpose of this study was to systematically review the instruments used to obtain anesthesia-specific patient satisfaction data and to determine the degree to which each instrument controlled for measurement error bias, such as poor survey design. By using an assessment and evaluation tool developed for the present study that held proven internal reliability and construct validity, we analy...
